Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.

The LX Series Industrial Boilers exceed expectations in both fuel-to-steam efficiency and its in-service efficiency. These units feature a computer-aided design that provides optimal heating surface transfer for an AFUE rating of 85 percent. A fire-tube boiler generally produces up to 83 percent fuel-to-steam efficiencies.

Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the …

Aug 19, 2019 · The reaction of having a fuel source, heat and an oxidizing agent allows for a reaction to take place. This keeps the heat source going. By heating tubes of water, and using fire tubes to heat a tank, steam is produced at extremely high pressures to produce enormous amounts of energy! We hope you enjoyed this short introduction to Boilers.

improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on boiler size and firing rate.

1 — Draining the boiler. Perform a bottom blow-off on the boiler before and then after shutdown to remove sediment and scale and to drop the unit's pressure and temperature. Once the unit is at zero psi gage pressure and water temperature is under 140°F, open an air vent and boiler drain to empty the boiler.
